ISalem Posted November 18, 2018 Share Posted November 18, 2018 (edited) The display sleep does not work correctly. Starting with Mac 10.12.4, the display sometimes does not wake up. The backlight works, there is no image, a black screen. Currently installed 10.14.1. All the same. If the display is sent to sleep, then sometimes it can wake up in a black screen with a working backlight. From the description, it is not difficult to guess that the display sometimes wakes up correctly and sometimes wakes up in a black screen. In the course of the experiments, I also saw that the display sometimes woke up and showed the boot screen (the Apple logo and progress bar), a second after that the desktop appeared. This behavior occurs only when the display wakes up on a black screen and then I close and open the laptop cover again, after which the boot screen sometimes appears for a second, but sometimes nothing appears, the system just hangs. I hope I clearly described the symptoms of the problem. The screenshot was taken after the experiment. I sent the display to sleep, then woke it up. He woke up in a black image with burning lights. Then I closed and opened the laptop bucket, pressed the space bar and waited a few seconds. After a few seconds, the boot screen with the Apple logo appeared and then the desktop appeared. Immediately made a screenshot.

SniperPiglet Posted November 21, 2018 Share Posted November 21, 2018 This problem occur with 10.12.4(and later) that installed HD5500. It is difficult to solve this problem. at least I could not find the solution. You must go to 10.12.3. This version is last MacOS for working perfectly on your PC.

Now I have version 10.12.3 on the main disk. The supplemental disk contains version 10.14.1 installed for testing. When I was looking for a way to solve this problem, I noticed that with this ig-platform 16260006 (Air 7.2) and kext X86PlatformPlugin.kext from OS 10.11.6 and OS 10.12.3, the display wakes up well, but sometimes wakes up on a black screen. If I delete this kext, the display always wakes up in a black screen. X86PlatformPlugin.kext.zip Edited November 21, 2018 by SeePurple Link to comment Share on other sites More sharing options...
